Dovecot, IMAP outlook reports error 0x800CCC0E cannot synchronize subscribed folders

dovecotimapoutlook

I have recently some issues with people using my email server.

They have problems with synchronizing folders on outlook, and I can't figure out what to do.

I found somewhere that I could extend a setting for imap connections:

mail_max_userip_connections = 20

which didn't really help, I was thinking about extending timeout of connection or something, but really can find anything like that.

In Thunderbird it seems to be OK.

here is dovecot -p result:

if anything could help please let me know what should provide.

RE: "0x800CCC0E cannot synchronize subscribed folders"

Had this happen today. I knew it had to be a client side error as dovecot logs had nothing but good news.

Resolved by doing the following:

  1. Close Outlook.
  2. Run the SCANPST.EXE utility on the particular imap account PST file in question. (Make a backup as well - trash it after you verify you are synced properly).
  3. Open Outlook.

...Fixed (for me at least.)

As a side note, I noticed I could not view my "Sent" items folder before I fixed error. It was the "Sent" folder in my case -> "Outlook cannot display folder" (if clicked/opened). I can now see/browse the 'Sent' folder properly, too.

To find location of scanpst.exe or the 'inbox repair tool' for all version of Outlook, consult:
